べくサーモスタツトセンサを作動させる能力にある。[Prior Art] In a conventional boiling water unit, the float chamber is placed beside the upper part of the boiling water unit, and is arranged such that the water level in the float chamber matches the level in the boiling water tank. When boiling water is withdrawn from the tank,
The water level in the float chamber and the boiling water tank is lowered, and the float arranged to float on the water in the float chamber is adapted to drop with the decrease in the water level in the float chamber. A float arm connected to the float opens the valve when the float drops to a predetermined level, such that opening the valve allows cold water under main pressure to enter the float chamber. A problem associated with the aquarium-fed boiling water unit is the ability to activate the thermostat sensor to turn on the heating element in the boiling water as soon as the water is withdrawn from the boiling water tank.

の加熱要素を作動するようにされている。In conventional boiling water units, jumper valves are provided to alternately block and circulate the flow of water from the main supply to the float chamber. Conventional boiling water units located above the maximum water level in the float chamber incorporate a wire mesh sleeve that houses the sensor. The sensor is provided for detecting the temperature of the water in the float chamber, and activates the heating element in the main tank when a drop in the water temperature in the float chamber is detected.

めになお、改良することが要求されていた。Conventional boiling water units mainly include a tongue on the float arm for diversion of some water entering the float chamber from the source to the wire mesh sleeve, where the sensor is connected to the float chamber from the main source. Once you sense the temperature of the water entering,
Activate the heating element. This arrangement has been found to be satisfactory, but nevertheless has been required to be improved for optimal operation of the unit.

かつ改善すべきさらに他の特徴である。[Problems to be Solved by the Invention] Still another problem that has arisen in the above-mentioned conventional boiling water unit is that a jumper valve for closing main water is caused by a rubber or a rubber substitute attached to a valve material. The problem is that a sealed body is incorporated. This seal is
The sealing pressure at the main water inlet is incomplete because the closing pressure tends to distort. As can be seen, this is yet another feature that is undesirable and should be improved.

ユニットを提供することを目的とする。Means for Solving the Problems Accordingly, the present invention generally comprises a main tank in which water is heated and discharges heated water, and a float chamber to which water is supplied under main pressure applied to the main tank, The float chamber, a nozzle for introducing water into the float chamber,
A temperature sensor, a float, a pivot arm mounted at one end to an upper portion of the float and pivotally pivoted about an opposite end, mounted at the pivot arm, at least partially surrounded by an inclined surface; A valve seat having a central groove portion, and a sealing body which is shaped to fit the valve seat groove portion and accommodates the valve seat,
Water flowing into the float chamber through the nozzle is first deflected by contacting the seal, and a portion of the water flows from the seal member along the inclined surface and contacts the sensor. By changing the sensor, the float rises to correspond to the rise in the water level of the float chamber, and the pivot arm is pivoted to bring the sealing body into close contact with the nozzle so that water flows into the float chamber. It is an object of the present invention to provide a boiling water unit characterized in that the boiling water unit is configured to prevent the occurrence of water.

The sprayed water impinges on a sensor operating the main tank heating element.

To accommodate. The float 3 and the float arm 4 are operated by a pivot (pivot arm) 5. The jumper valve, indicated generally at 15, is opened as shown in FIG. 2 to allow water 10 to enter float chamber 1 through nozzle 11. The jumper valve has an inclined surface 14 and a side wall 12. The pressurized water entering the float chamber collides with the jumper valve sealing member 13 and is then dissipated to the float chamber 1,
Some water 10 forms a spray 8 which impinges on a wire mesh sleeve 6 containing a sensor 7. Some water mixed into the spray 8 activates the main tank heating element.

Rises as the surface level of the rises. Eventually, when the jumper valve 15 reaches the position shown in FIG. 3 with respect to the pipe 11, the water is prevented from entering the float chamber 1. As can be seen, the pressure of the water 10 causes the seal 13 to expand, and thus the inflatable gap comprises the seal 13 and the valve seat 16.
Are left as shown in FIG. Sealing member 13
This expansion gap is completely occupied by the expanded sealing member 13 which nests over the valve material 16. When the water level in the float chamber drops again and water again enters the float chamber from the pipe 11, the jumper valve 15 is again in the position relative to the pipe 11 shown in FIG. 2 and the seal 13 is shown in FIG. The arrangement is as follows.
The preferred thickness of the seal 13 is on the order of 2 millimeters and the preferred open gap 17 is about 1 millimeter.

A central circular cutout having a circular horizontal cross section having a sloped surface at least partially surrounding the valve seat and further having a vertical outer wall, and an inner portion of the body for receiving a cylindrical seal; Since the wall of the valve seat between the notch portion and the outer wall includes a seat (groove) portion and is sloped like a frusto-conical surface, it is possible to improve the above-mentioned disadvantages of the conventional jumper valve. A possible floater jumper valve can be provided.
